To all whom it may concern:

Be it known that l, lillcimnL ABAnNo, a

citizen of the l nitetl States, and a resident of the city of New York,borough of Manhattan, in the county and State of New York, have inventeda new and improved Brick-Heidi st, of, which the'folloiving is a lull,clear, and exact description.

This invention relates to a new and im proved device for holding; thebrick securely in iilinenient and permitting; grounds or planking to besecured to the walls.

It has been found in practice quite clililcult to secure grounds for themolcl hoards,

or planking of any kind, to brick, block,

tile or other wall, such as that composed of hollow fii'c-prooi hriclrs,blocks, tiles, concrete or other huiltling elements. ll has also beenfound difficult to hold fur-ring of any suitable height, to brick,block, tile, concrete, or other impenetrable Walls.

An object, therefore, ot' this invention is to provide a hohlfast of a.simple and inexpensive structure. which can readily be inserted atsuitable intervals between juxtaposed building elements anil'form ameans for securing the bricks or other building members in alincmcnt,and also a soft foundation, into which nails or other fastening devicesmay he '5 iron, to supportgrounds, planking, or fuming, in position onthe Walls.

A l r 'her object of this invention is to proviilma holtlfast or clamp,which can be adjusted to various sizes of bricks. in a Slil'k pic antiquick manner, anti which will have a suliicientlf. roughened exterior topermit the ltfilllCSlOI] oi. plaster therein, and the roughoning beingof such a form that, it will not interrupt th passagenails into thehotly of the holclfasl, which preferably formed, of some soft material,such as WOOCl. These and further ohjeris, together with the constructionanal combination of parts, will he more iully described hereinafter andparticular, forth in the llfier-encc is to he llil-(l. to the ncco n tiingg (ll'ttW .orming a part of issnec ication, in whicl similarcharacters oi reference indicate corresponding; ports views, and inWhich-- Figure l is a Vi w e 1 the improved device use-L a "l s suitablemeans,

shows the invention as applied to a concrete Wall.

rate parts of my invention as embodied in the form shown in thedrawings, 1 indicates the holclfast orv clamp, which includes a bodyportion 2, which may he of a ny suitable form and material, preferably arectangular block of wood. The size of this block may be variedaccording to conditions, and also, if desired, the material. Thematerial, however, must be of such a nature that a nail can be driventherein, to form a support for outside grounds, planking, or ihe like.lnthe claims, I have clesin'nafied this material by the term Wood, hutdo not Wish to be limited Io Wood as such, but any equivalent inaterialwhich will yield to the driving; of a spike in a compressible manner andyet tcnaciously hold the spike, or like fastening" device. when oncedriven in.

On facing edges are preferably provided means for roughcnin; the surfacethereof, such as a wire netting- S, which in this case is shown to heformed expanded metal suitablycorrugated to form sufiicientirregularity. so as lo holcl plaster, if it is desired to plaster theWall which this invention is used.

For he purpose olfhouling the block in the place in which it is put,Whether between :1 pair of juxtaposed bricks or between fin-ring,between the horly of a concrete Wall, there are provided plates 4: and5, which exi'entlwn the face of the walls in which the device islocated, and are tied to IiCl'lOiLllQZ by means of suitable lies 6,Which may be in the form oi. plates having tongues "l, which e enilthrough slots 8 in th plates 4 anti 5. l4 8 n he held in "position on thhocly i through suitable openings 10 in the ties, into the horl of theblock.

The plate anti. 5, Where they extend over the hotly horizon of block,may be pro-' rid is Sllloliblfii openings 11, through tion on the block.It is preferred. that the plates anilitongues be made of suitablemalleable material, so that they can-be bent over by a slight blow, toconform to slight differences in thickness of the bricks or wall,

I due to slight inaccuracies in the making.

'lhe combination of a pair of plates and a pair of ties forms what istermed a bracket.

" clamp. It is preferred that a plurality of these clamps be providedfor each block,-

preferably two, one located adjacent each: end of the block.

The utility of the device will be readily understood when taken inconnection with the above description. In the case where the holdfast isused in connection with a terracotta or fireproof brick wall, as showninFig. .1, a plurality of the holdfasts are inserted between adjacentbricks, both on the straight surface and where a curved surface isprovided, as also illustrated in Fig. 1. The number of holdfastsinserted in the wall is immaterial, and they can be inserted atsuitableintervals and a sufficient number provided to hold the grounds,indicated at 12 in Fig. 1. It will readily be seen that these holdfastslessen the amount of cement which is inserted to form. a strong wall, inthat they tie the 'bricks together and prevent the wall from sagging. Itwill also be .seen that the grounds 12 may be readily secured inposition by driving nails through the grounds and through the woodenbody portion of the holdfasts. The holdfasts themselves will readilytake the plaster, inasmuch as their exposed surfaces are roughened bythe expanded metal.

In Figs..4= and 5, my device is shown as being used in connection. witha brick wall, for lholding the fireproof furring to the surface thereof.In this connection, the holdfasts-are secured to the brick wall atsuitable spaced intervals, by driving spikes 13 I through the holdfastsand. between the bricks of the wall, The retaining strips 14 may be thenattached to the holdfasts, to hold the furring, indicated at 15, inplace.

In Fig. 6, my device is shown as applied to a concrete wall, wherein itw1ll be seen .that a plurality of these holdfasts may bev inserted atsuitable intervals in the concrete Wall being laid, and when finished,these holdfasts will not only strengthen the wall at intervals, but willalso form a base on 'which planking or other material may be nailed bydriving spikes or nails therethrough.

' it will readily be seen that in all of these structures, even ifpounding is done on one side' of the Wall, itwill not force the holdfasts, or any portion thereof, through the wall, so as to disturbmaterial placed on the opposite side of the wall, as is usually thecasein such devices as are now in'use.

', While I have shown one embodiment of my invention used in severaldifferent ways, I do n t wish to be limited to the specificdetails tereof, butdesire to be protected in' various changes, alterations andmodifica tions, both in the holdfast and in its application, which maycpme within the scope of the appended claims.

Having thus described my invention, I I
